OEM Upper Control Arm Bushing and Positive Caster

i don't know why either but I just installed a set in my 67 and they fit perfectly. Only thing is the directions say to point the arrow toward the ball joint. Thats incorrect. One needs to point away to get most caster
That is right. To get max positive caster you need to install then as shown in the illustration below.
